Restrictive red-cell transfusion,
does it really help with Improved six-week survival versus a liberal 9 g/dL threshold?
research showsThe grade is B. Villanueva randomized 921 patients, 461 versus 460. Six-week mortality was 23 (5.0%) with the restrictive strategy and 41 (8.9%) with the liberal strategy, HR 0.55 (95% CI 0.33 to 0.92). Further bleeding was 10% versus 16%. No independent trial confirmed the same mortality question, giving B with 76 points.
ads claimRestrictive transfusion does not mean refusing transfusion. It is a hospital protocol combining a hemoglobin threshold and target with bleeding control, vital signs, and ischemic symptoms.
Useful facts when choosing a product
- The trial started transfusion below 7 g/dL and targeted 7 to 9 g/dL.
- All 921 were randomized; six-week deaths were 23/461 versus 41/460.
- Several high-risk cardiovascular conditions were excluded and require separate judgment.
What the research actually shows
Villanueva randomized 921 patients to transfusion below 7 g/dL with a 7-to-9 target or below 9 g/dL with a 9-to-11 target. Six-week survival was 95% versus 91%, mortality HR 0.55 (0.33 to 0.92), and rebleeding 10% versus 16%. Fundacio Investigacio Sant Pau funded the trial. NHS Blood and Transplant Research and Development funded TRIGGER, but its cluster-feasibility design, thresholds, and primary clinical outcome differed.
Why this is classified as B (76)
A large nonprofit-funded randomized trial reduced death and rebleeding, but independent confirmation of the same 7-versus-9 g/dL survival question is absent, giving B with 76 points.
Counterpoint. Verdict 2324 is D with 34 points for transfusion in acute myocardial infarction, a different population and threshold question that was not pooled here.
Rejudgment record. Cross-check applied — The Villanueva paper and NCT00414713 were compared with TRIGGER and ISRCTN85757829 for thresholds, populations, primary outcomes, analysis, and funding
| Endpoint | H | Hard endpoint - actual events such as death |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
The scoring table and the verdict agree (B).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Improved six-week survival | B | Mortality was 5.0% versus 8.9%, HR 0.55. |
| Reduced further bleeding | B | Further bleeding was 10% versus 16%. |

Evidence Table
| Study | Design | Sample | Funding | Endpoint | Result | Weight |
|---|---|---|---|---|---|---|
| Study 1 | Single-center stratified randomized clinical trial | 460 | Fundacio Investigacio Sant Pau | Six-week survival and further bleeding | Deaths 23/461 (5.0%) versus 41/460 (8.9%), HR 0.55 (0.33 to 0.92); rebleeding 10% versus 16% | Pivotal nonprofit-funded large hard-outcome trial |
| Study 2 | Six-hospital cluster-randomized feasibility trial | 1 | NHS Blood and Transplant Research and Development | Feasibility and 28-day further-bleeding clinical outcome | It evaluated feasibility of 8 versus 10 g/dL policies and was not a confirmatory mortality trial. | Contextual evidence not counted as direct mortality replication |
